Bengal Military Orphan Society

Bengal Military Orphans were sent to either:

A. The Upper Asylum in Calcutta (for children of Officers) or

B. Lower Asylum, also in Calcutta, (for children of NCOs or soldiers).

Both were entitled to a pension and the Pension Records for orphans of officers are generally available in the IOR L/AG/21/27 series.

FIBIS database: Bengal Upper Orphan School 1820-1857 . Alphabetical list of orphaned children of officers of the Bengal Army, 1820-1857. The data include Dates of Birth, Dates of Admission to and Discharge from the Asylum, Name of father, etc. These were orphans who had returned to Britain and whose guardians had received payment there from the Bengal Military Orphan Society. They were no longer physically in an Asylum, so the date of discharge from the Asylum is rather the date of discharge from the Society, when benefits were finalised.
